I don't have a Christian listed in my tree, but I do have a family group sheet for a Peter Freidrich that I haven't gotten around to entering into Ancestry yet. I have a whole file box full of family group sheets plus more that wouldn't fit. According to the info I have he was born on 2/22/1896 in Neuberernd, Schleswig, Germany, married Carolyn Link in 1934 in Chicago, Cook, IL. He died on 4/1/1970 and was buried in Clarendon Hills, IL. He was the son of Detlef Hansen and Maria Eckhart and had one son, Jack Detlef. I don't know if this is the Peter Hansen you are looking for. From the info on the family group sheet it looks like he stayed in Illinois, but two of his brothers settled in the Woodward, IA area, which is in Dallas county. They are August Henry and Amos Hansen. There may be more of the siblings that settled in that area, as some of them are buried in Woodward Cemetery, but I will have to go through their hints and see what the census records say. So far most of the info I have on the family is from the Woodward Centennial Book that was published in 1983.
Let me know if this is the family you are looking for and I will see if there are any pictures in the book I can scan and upload.
